Definitions

  • the interrogatable coherently viewable structure was spread over the entire area of the device thus resulting in either a degraded visual authentication device or a weak coherently detectable structure.
  • the coherent structure was highly localised into small areas making unskilled interrogation particularly in the field relatively difficult in terms of locating and aligning to the desired feature.
  • covert images Upon laser reconstruction and imaging the covert images will generally replay at different angles to a reference co-ordinate system for the device (typically a reference plane containing the physical plane of the device and a normal to the device). They will thus replay at different angles to the normal to the device and would normally have an angular separation of the some size or greater than their angular sub-tense to ensure minimal cross-talk between them and ease of viewing.
  • a reference co-ordinate system for the device typically a reference plane containing the physical plane of the device and a normal to the device. They will thus replay at different angles to the normal to the device and would normally have an angular separation of the some size or greater than their angular sub-tense to ensure minimal cross-talk between them and ease of viewing.
  • covert images form their focussed images at a plane away from the real plane of the device the covert images will be separated on their image plane by at least a distance corresponding to the dimensions of the covert images.
  • a particularly useful method for generating electron beam generated structure of the correct replay property is to form repeated groups of pixels or other shapes consisting of groups of very similar diffraction gratings, varying slightly in pitch and orientation between them, and arranged to generate the designed covert out of plane image by the superposition of their diffracted replays.
  • linear structure in a usual embodiment of this device the line width would be constant, and very small compared to the length and generally the line would be continuous.
  • linear widths of variable thickness along their length may be particularly suitable for certain applications of the device for example when a hot stamping foil diffractive device is blocked onto rough paper (e.g. banknote paper) where it may useful to vary or thicken the line width locally to localise the patterns more to reduce degradation due to surface roughness or where the line is occasionally broken for example at interlocks and cross-over points with other graphics or to form a dashed line shape, for example - again where the device is substantially linear with small breaks of size comparable only to the line width.
  • the linear structures may be in the shape of lines, curves, circles or other suitable shaped graphics characterised that the structure is made up of a linear region within the dimensions given whose length is substantially greater than its width.
  • Suitable memorable optical events could be for example an apparent expansion or contraction of a set of concentric line features in the form of a circle or rosette shape, for example, an apparent rotation around a guilloche line pattern or an apparent image switch on tilting the device where the shape defined by the line patterns mutates from on recognisable defined graphical or alphanumeric shape seen as a line shape to another different defined shape either in a sharp switching movement or a well defined switching movement.
  • a guilloche pattern or design being a significant part or component of the design, say of 5 - 10 mm in size in one direction, possibly with the covert message bearing line structure forming part of this pattern (for example as a set of key-lines or underlines to a main or part of a diffractive or holographic image emblem).
  • covert message bearing line structure forming part of this pattern (for example as a set of key-lines or underlines to a main or part of a diffractive or holographic image emblem).
  • covert message bearing line structure forming part of this pattern (for example as a set of key-lines or underlines to a main or part of a diffractive or holographic image emblem).
  • covert message bearing line structure forming part of this pattern (for example as a set of key-lines or underlines to a main or part of a diffractive or holographic image emblem).
  • linear structure forming a guilloche border area to a main design to form both a secure animated visual gui
  • One useful form of the structure has the main diffractive carrier grating spatial frequency of the covert image structures being less than that of the surrounding visual hologram (i.e. a larger carrier diffraction grating spacing) so that the covert images replay through a smaller diffraction angle than the main image to reduce image blur on the out of plane features and also to angularly separate then covert features the main visual image features to aid in ease of authentication.
  • Example (25) shows how such a device may be combined with other diffractive graphics by for example forming a discrete set of key-lines around a main graphical element.
  • Example (26) and (27) shows how a nested complex line structure such as a guilloche pattern may be from such devices and used to provide apparent movement and animation effects such as rotations and expansions.
  • Example (28) illustrates how the device could be made to reconstruct its images when the overall device is rotated by 90 degrees in its plane away from the replay direction of the primary diffractive image so allowing the device to be spread over a large area of the overall visual security device to make authentication particularly straightforward.
  • FIGURE 8 illustrates the structure of Figure 7 under coherent illumination (14) of a portion of the coherently readable structure (32) showing examples of the various forms the corresponding coherently viewable images (set of 5 images 45 and 46) could take and what would be imaged at various angles on rotating the device around an axis (41).
